a title too ambitious for a book like this
90% of the book, a brochure of Grander products; the remaining 10%, a copy&paste of Schauberger's only biography ... in brief, a book to know that there are a couple of guys called Grander and Schauberger, but not very much else. Definitely, I would recommend it only as a light reading but not for people who's looking for a comprehensive study about water's secrets.
